Description
Technical Field
The invention relates to an expansion module for a load carrier, in particular a bicycle carrier, which is fastened or fastenable to a vehicle and comprises at least one profile rail for receiving a load, in particular a bicycle, the expansion module having at least one expansion profile rail for receiving a load, in particular a bicycle, and at least one fastening unit for attaching the expansion profile rail to the profile rail of the load carrier, the fastening unit having a support element which is connected at one axial end region thereof to the expansion profile rail and at the other axial end region thereof to a mounting device.
The invention further relates to a load carrier, in particular a bicycle carrier, having a coupling device for fastening to a vehicle, in particular a motor vehicle, and a carrier frame connected thereto, on which carrier frame at least one profile rail for receiving a load, in particular a bicycle, is arranged.
Furthermore, the invention comprises a method for fastening an expansion module to a load carrier, in particular a bicycle carrier.
Background
Bicycles are commonly transported using a load carrier for fastening to the rear end of a vehicle, in particular a motor vehicle such as a car. Typically, such load carriers comprise coupling means at their front end area, which coupling means are typically designed such that the load carrier can be fastened to the hitch ball of a conventional trailer coupling. Such a load carrier for transporting a bicycle comprises a carrier frame to which profile rails for receiving wheels of the bicycle are fastened. These profile rails are usually arranged transversely to the direction of travel and substantially horizontally and comprise fastening means for fastening the bicycle to the profile rails.
Commercially available load carriers are typically designed to enable a limited number of bicycles to be transported on the load carrier. It is considered in part disadvantageous that the load carrier is not capable of carrying a greater number of bicycles than the configuration determines.
thus, DE 202017103523U 1 proposes a bicycle carrier expansion system to enable the capacity of an existing bicycle carrier to be increased by one bicycle. What is specified here is the fastening of a support element to an existing profile rail of a load carrier, said support element carrying an extended profile rail for receiving another bicycle. For fastening to the profile rail, the support element comprises a profiled mounting device which engages in a groove formed in the outer profile of the profile rail. Furthermore, an engaging element is pivotably arranged on the support element, which engaging element can engage in a groove arranged on the opposite side of the profile rail. For mounting, the support element is clamped by inserting it into the recess and rotating it about the latter, so that the engagement element is clamped in the opposite recess and the support element is thus fixed with the expansion profile rail by form fit.
A disadvantage of this construction is partly to be regarded as being that the form of the fastening mechanism is very fragile and that only one engaging element is provided for fixing the support element to the existing profile rail. If the engaging element is accidentally touched, the support element may loosen, with the result that the expanded profile rail, to which the bicycle is additionally fastened, loosens from the load carrier. Such an unintentional movement of the engaging element may also be caused by vibrations, for example when driving over bumps in the road.
Furthermore, the proposed structure results in that the catching means must be designed to match its cross-sectional profile due to the direct attachment of the support element to the existing profile rail. As a result, an extension system designed in this way can only be fastened to profile rails of one design, and this makes it necessary to provide a large number of versions of profile rails on existing load carriers.
Disclosure of Invention
The object of the present invention is therefore to design an expansion module for a load carrier such that the above-mentioned disadvantages can be avoided and in particular to design the fastening of the expansion module to the load carrier such that it can also withstand higher mechanical loads.
With an expansion module of the initially specified type, this object is achieved by a fastening unit which also has an adapter unit which is or can be detachably connected to the mounting device by means of a fastening mechanism in order to be fixed to the profile rail of the load carrier.
the idea behind the invention is therefore to attach an adapter unit to the profile rail of the load carrier, which adapter unit can also be held on the load carrier for a long time, if desired, and to design the mounting device such that it can be connected to the adapter element. It is thus possible to design the mounting device so as to be mechanically robust, so that at the same time accidental opening and thus detachment of the expansion profile rail to which the load is fastened can be reliably avoided. Furthermore, the provided adapter unit enables the same embodiment of the fastening unit and the extended profile rail for different types of profile rails arranged on the load carrier to be achieved, since the adapter unit only has to be designed to match the profile rail. Thus, a large number of versions of the fastening unit can be avoided.
In a further embodiment of the invention, the adapter unit comprises a plurality of adapter elements which are supported or can be supported and which are screwed or can be screwed to one another in order to be supported on the profile rail in order to be fixed to the profile rail by force fit and to prevent a movement of the adapter unit in the longitudinal direction of the profile rail. For example, the adapter elements are or can be screwed to one another in order to be supported on the profile rail. As an alternative, the adapter elements can be coupled to one another by hook engagement on one side of the profile rail and screwed to one another on the opposite side of the profile rail in order to be supported on the profile rail.
preferably, the adapter elements are designed such that they can be placed flat against the outer contour of the profile rail and in particular engage with the outer contour of the profile rail by means of a form fit in order to prevent a movement transverse to the profile rail. For example, the adapter unit can have two adapter elements which engage around the profile rail from above and below and are screwed to one another and are thus supported on the profile rail, with the result that the adapter unit is fixed to the profile rail by force fitting. Such a threaded connection of the two adapter elements constitutes a permanent connection which can only be released by means of a tool and is therefore also advantageous in terms of the risk of accidental opening of the connection.
Furthermore, the support element can be detachably connected, in particular screwed, to the extension profile rail. In a preferred embodiment, the expanded profile rail is formed concavely curved on its upper side, in particular in a V-shape. In this way, the wheels of the bicycle can be positioned on their upper side transversely to the extended profile rail.
furthermore, provision can be made for at least one tensioning device, in particular two tensioning devices, for fixing the bicycle to the expansion profile rail to be assigned to the expansion profile rail. The tensioning device can be held displaceable along the expanded profile rail and can comprise a base body with a bearing surface for a bicycle wheel, which can be removably fixed to the expanded profile rail.
In a preferred embodiment of the invention, the tensioning device has a clamping device for fixing the base body to the extension profile rail. For this purpose, the expansion profile rail can have a particularly T-shaped groove, and the clamping device can comprise a clamping screw which can be screwed to a slot nut which can be displaced within the groove in order to fix the tensioning device to the expansion profile rail by force fit.
The two wheels of the bicycle are fixed in the longitudinal direction of the expanded profile rail by means of the tensioning device. The tensioning device, which can be displaced along the expansion profile rail, makes it possible here to adapt the expansion module flexibly to bicycles of different sizes.
The tensioning device may comprise a tensioning element fastened to the base for clamping the bicycle wheel. Preferably, the tensioning element is in the form of a tensioning belt for encircling a wheel of the bicycle, which tensioning belt is in particular flexibly connected at one end region thereof to a base body of the tensioning device. At its free end region, the tension belt can have teeth which can be locked into corresponding catch fasteners which are also fastened to the base body of the tensioning device.
Clamping the bicycle wheel prevents accidental detachment of the bicycle, in particular jumping out of the concavely curved upper side of the extended profile rail. For the fitting, the tension band is placed around the wheel between the spokes of the wheel and in its free end region in a catch fastener fastened to the base body of the tensioning device. The flexible mounting of the tension band is advantageous in respect of loading bicycles of different sizes and different wheel sizes, since the angle at which the tension band rests on the bicycle wheel can be adapted.
In a further embodiment of the invention, the mounting device has a housing body which is open, in particular on its underside, and two bolts which are arranged substantially parallel to the extended profile rail and parallel to one another on the housing body, which bolts are laterally, in particular perpendicularly to the extended profile rail, one behind the other, and the adapter unit comprises two recesses assigned to the bolts, with which two bolts of the mounting device can engage in order to attach the fastening unit.
Preferably, the recesses formed in the adaptor unit extend parallel to each other and are aligned with each other. The bolts here can be displaced relative to each other between a mounting position and an engagement position in which the bolts engage with the recessed contour and can be locked.
in a preferred embodiment, one of the two bolts is in the form of a fixed bolt which is firmly connected to the housing body, and the other bolt is in the form of a bolt which is movable between the mounting position and the engagement position. The movable bolt can here be guided in a slotted hole formed in the housing body. In this case, a locking device is provided for locking the movable bolt in the engaged position.
The idea forming the basis of this embodiment is to mount the fastening unit on the adapter unit such that the two bolts engage in corresponding recesses formed in the adapter unit by means of a form fit. In the mounted position, the bolts, which are displaceable relative to one another, are introduced into the grooves facing one another and then moved into the engaged position and locked, so that the bolts bear against the recessed contours facing one another and the fastening unit is prevented from falling out.
In a further embodiment of the invention, a tensioning force is applied to the movable bolt in the direction of the fixing bolt by means of an elastic tensioning element, in particular by means of a helical tensioning spring, the tensioning element being in particular fastened to the fixing bolt. The movable bolt can be connected to a tensioning disc which protrudes from the housing body through an opening formed in the housing body on the front side. The tensioning disc can have a pivot joint in its region protruding from the housing body, to which a locking lever is fastened for locking the movable bolt in the engaged position.
Furthermore, the locking lever can have two outer faces, which are in particular flat, one of which faces lies in the mounting position and the other of which faces lies flat against the in particular flat front face of the housing body in the engagement position of the movable bolt. The two faces of the locking lever may preferably be arranged at 90 ° to each other and/or a chamfer, in particular a fillet, may be formed between the two faces.
The lock lever can be formed such that a distance between the pivot joint and a face that contacts the housing main body in the engagement position is greater than a distance from the face that contacts the housing main body in the mounting position.
Locking of the movable bolt thus takes place such that in the engaged position the pivot joint projects further forward of the front face of the housing body than in the mounted position, and the face of the locking lever that is further away from the pivot joint abuts against the front face of the housing body. In this way, the locking lever holds the movable bolt against a tension in the direction of the fixed bolt in the engaged position. If the movable bolt is to be brought into the mounting position, the lever is tilted backwards, drawing the bolt back into the mounting position by means of the elastic tensioning element, and the other outer face of the locking lever abuts on the front face of the housing body.
The mounting device may further comprise a cover member for closing the open upper side of the housing body.
The object of the invention is also achieved by a load carrier of the type specified in the opening paragraph, which has an expansion module according to the invention removably fastened to the profile rail.
furthermore, the object of the invention is achieved by a method for fastening an expansion module according to the invention to a load carrier, in particular a bicycle carrier, comprising the following steps:
Providing an expansion module according to the invention;
Securing the adapter unit to a profile rail formed on the load carrier;
A fastening device and an extended profile rail connected to the fastening device for receiving a load, in particular a bicycle, are connected to the adapter unit.

Detailed Description
a load carrier 1 according to the present invention in the form of a bicycle carrier is shown in figures 1, 2 and 3.
The load carrier 1 comprises a load carrying frame 2, on the front side of which frame 2 a coupling device 3 is provided for fastening to the vehicle. Two profile rails 4, 5, which run parallel to one another and transversely to the carrying frame 2 and in which the wheels of the respective bicycle can be positioned, are arranged on the carrying frame 2. For this purpose, the profile rails 4, 5 are formed so as to be concavely curved upwards.
The profile rails 4, 5 are not continuous, but each have two sub-sections 4a, 4b, 5a, 5b projecting from opposite sides of the carrying frame 2 and formed to each receive a bicycle wheel. Furthermore, the load carrier 1 comprises a fastening frame 6, on which fastening frame 6 adjustable fastening elements 7 are arranged for additionally fixing a bicycle frame, not shown.
An expansion module 8 for receiving another bicycle is secured to the bicycle carrier 1. The expansion module has an expansion profile rail 9, the expansion profile rail 9 being formed so as to curve concavely upwards, to be continuous and to extend parallel to the profile rails 4, 5. As with each of the two profile rails 4, 5 of the bicycle carrier, exactly two tensioning devices 10 are assigned to the extended profile rail 9 for fixing the bicycle to the extended profile rail 9.
The tensioning device 10 is held so as to be displaceable along the expanded profile rail 9 or the profile rails 4, 5 and comprises a base body 11, which base body 11 can be detachably fixed to the expanded profile rail 9 or the profile rails 4, 5 and has a bearing surface 12 for the bicycle wheel.
In particular, the extension profile rail 9 or the profile rails 4, 5 each have a T-shaped groove 13. Each tensioning device 10 has a clamping device 14 with a clamping screw 15, which clamping screw 15 can be screwed with a slot nut 16 that can be displaced in the T-shaped groove 13 in order to fix the base body 11 to the expanded profile rail 9 or to the profile rails 4, 5 by force fit.
Each of the tensioning devices 10 further comprises a tensioning element 17 in the form of a tensioning band fastened to the base body 11 for clamping the bicycle wheel. In one of its end regions, the tensioning element 17 is flexibly connected to the base body 11 of the tensioning device 10 and is designed to be wound around a bicycle wheel. In its free end region, the tensioning element 17 has teeth 18, which teeth 18 can catch in corresponding catch fasteners 19 fastened to the base body 11 of the tensioning device 10.
The expansion module 8 further comprises two fastening units 20 for attaching the expansion profile rail 9 to the profile rail 4 of the load carrier 1.
each of the two fastening units 20 has a support element 21, which support element 21 is screwed in its one axial end region to the extended profile rail 9 and in its other axial end region to a mounting device 22.
A corresponding adapter unit 23, which is detachably fastened to the profile rail 4, is assigned to the mounting device 22. In particular, the fastening units 20 each have an adapter unit 23 which is fixed to the profile rail 4 of the load carrier 1. Each adapter unit 23 has two adapter elements 25, 26, which adapter elements 25, 26 engage around the profile rail 4 from above and below and are formed such that they engage with the outer profile of the profile rail 4 in a form-fitting manner. The adapter unit 23 is fixed to the rear profile rail 4 of the load carrier 1 by screwing the adapter elements 25, 26 to each other against the profile rail 4 and thus to the latter by force fitting, and movement of the adapter unit 23 in the longitudinal direction of the profile rail 4 is prevented. In particular, the adapter elements 25, 26 are screwed to one another on opposite sides of the profile rail 4 (see fig. 3).
As shown in fig. 3a, the adapter elements 25, 26 can also be connected in a different manner in order to clamp against the profile rail 4. In this embodiment, the adapter elements 25, 26 are joined to one another on one side of the profile rail 4 by hook engagement. To this end, hooks 43, 44 are formed on the two adapter elements 25, 26, said hooks 43, 44 engaging each other such that at this connection point the upper adapter element 26 cannot be lifted from the lower adapter element 25. Alternatively, a slot or cut-out can be formed in the lower adapter element 25, into which the hook 44 of the upper adapter element 26 extends.
on the side of the profile rail opposite the hook engagement position, the two adapter elements 25, 26 are screwed together in order to support the adapter elements 25, 26 on the profile rail 4.
In order to fix the mounting devices 22 to the adapter units 23, the mounting devices 22 each have a frame-like housing body 27, the open upper side of which is closed by a cover element 28. Two bolts 29, 30 are held on the housing body 27, said two bolts 29, 30 being arranged parallel to the expansion profile rail 9 and to each other, and said two bolts 29, 30 being situated behind each other perpendicular to the expansion profile rail 9 and passing through the housing body 27.
One of the two bolts is in the form of a fixed bolt 29 which is firmly connected to the housing main body 27, and the other bolt is in the form of a movable bolt 30, the movable bolt 30 being guided in a slotted hole 33 of the housing main body 27 in such a manner as to be movable between a mounting position closer to the fixed bolt 29 and an engagement position farther from the fixed bolt 29, and being lockable in the engagement position.
The adapter units 23 each comprise two recesses 31, 32 assigned to the bolts 29, 30, extending parallel to one another and aligned with one another, with which recesses 31, 32 the two bolts 29, 30 of the mounting device 22 can engage. In the engaged position, the bolts 29, 30 abut on the outside against the contour of the recesses 31, 32.
a tension force is applied to the movable bolt 30 in the direction of the fixing bolt 29 by means of a coil tension spring 34 fastened to the fixing bolt 29. The movable bolt 30 is connected to a tension disc 35, which tension disc 35 protrudes from the housing main body 27 through an opening 36 formed in the housing main body 27 on the front side. In its region projecting from the housing body 27, the tensioning disc 35 has a pivot joint 37, to which pivot joint 37 a locking lever 38 is fastened for locking the movable bolt 30 in the engaged position.
The locking lever 38 has two adjacent flat outer faces 39, 40, the two adjacent flat outer faces 39, 40 being arranged at an angle of 90 ° to each other and a rounded corner 41 being formed between the two adjacent flat outer faces 39, 40. In the mounted position, one 40 of the two faces of the locking lever 38 sits flush against a flat front face 42 of the housing body 27, and in the engaged position of the movable bolt 30, the other 39 of the two faces sits flush against the flat front face 42 of the housing body 27. The distance between the pivot joint 37 and the face 39 which comes into contact with the housing main body 27 in the engaged position is greater than the distance from the face 40 which comes into contact with the housing main body 27 in the mounted position.
The expansion module 8 according to the invention is fastened to the load carrier 1 by first fastening the adapter unit 23 to the profile rail 4 previously formed on the load carrier 1 and then connecting the fastening unit 20 and the expansion profile rail 9 connected thereto to the adapter unit 23 in order to receive a bicycle.
